facial vein

The common facial vein is not present in all individuals.

They studied buccal segments of the human facial veins in vitro.

A common misconception states that the facial vein has no valves, but this has been contradicted by recent studies.

No facial veins or clumps of bristly warts.

This is possible because of venous communication (via the ophthalmic veins) between the facial vein and the cavernous sinus.

Diagnosis is generally achieved by signs such as cranial bruits and symptoms such as expanded facial veins.

However, substantial drainage via the ophthalmic, infraorbital, and deep facial veins communicates with the cavernous sinus (ref).

It descends behind the auricula, and joins the posterior division of the posterior facial vein to form the external jugular.

It also has a common trunk into which drains the anterior branch of the retromandibular vein, the facial vein, and the lingual vein.

The venous drainage system of the cheek is predominantly formed by the anterior facial vein, which subsequently communicates with the internal jugular vein.

The facial vein (or anterior facial vein) is a relative large vein in face.

Infections may also be introduced by facial lacerations and by bursting pimples in the areas drained by the facial vein.

The internal jugular vein is formed by the anastomosis of blood from the sigmoid sinus of the dura mater and the common facial vein.

There are also connections with the pterygoid plexus of veins via inferior ophthalmic vein, deep facial vein and emissary veins.

The anterior facial vein receives a branch of considerable size, the deep facial vein, from the pterygoid venous plexus.

The anterior facial vein lies lateral/posterior to the artery, and takes a more direct course across the face, where it is separated from the artery by a considerable interval.

In patients with thrombophlebitis of the facial vein, pieces of the clot may break off and enter the cavernous sinus, forming a cavernous sinus thrombosis.

(c) supramandibular, on the outer surface of the mandible, in front of the Masseter and in contact with the external maxillary artery and anterior facial vein.

Unlike veins from other areas of the skin, facial veins responded with an active myogenic contraction to passive stretch and were therefore able to develop an intrinsic basal tone.

This is likely not the case in that there are descriptions of the use of thumb lancets in horses for opening the facial vein and for bleeding cats and dogs.

But even with one way valves, blood flow between the facial vein and cavernous sinus can spread infection from the face; it is the direction of blood flow that is important.

The Kalendru didn't wear rank insignia any more than strikers did in the field, but one of the silent captives had the prominent facial veins that were signs of nobility among the species.

Finally, just as Banchert felt sure the distended veins in the face before him would burst, the tirade ceased as if switched off, though the neck and facial veins still remained engorged.

The anterior part contains the submandibular gland, superficial to which is the anterior facial vein, while imbedded in the gland is the external maxillary artery and its glandular branches.

The medial angle of the eye, nose and lips (known as the danger triangle of the face) usually drain through the facial vein, via the ophthalmic vein through the cavernous sinus.
